True, just as the whole SAN is just another layer layer of complexity for booting and swaping : zoning and selective storage presentation errors are common, not to mention software shortcomings.It seems to me that volume managers, aka LVM or the like, is where folks should be heading and the faster we can move them in that direction the better. The volume managers provide so much more flexibility than partitions.Maybe so. But they also add another layer of complexity forbooting. I'd like the steps between me and a successful boot to be as complex as required but no more so.
System on SAN is just a bit more risky. Not doing it also cuts down on the main use for partitions.
Big data volumes can be handled just fine by storage arrays internal volume managers.
My opinions, anyway. So subject to frequent oscillations ;) Regards, cvaroqui
